During his career as a businessman and politician, Donald Trump has had a noted relationship with the sport of American football, both at the professional and collegiate levels. Since the 1980s, he has had a strained relationship with the National Football League (NFL), the largest professional American football league in the world. A 2018 article in Business Insider labeled Trump's relationship with the league "The Pigskin War", calling the NFL "his oldest rival". That same year, sportswriter Adam Schefter of ESPN stated that Trump has "his own little vendetta against the NFL", while Ed Malyon, the sports editor of The Independent, stated in 2019 that, "Trump has long waged war against the NFL".
